143ml Clear Glass Yogurt Jar With Plastic Cap to Senegal

Newray’s Breakthrough in Lightweight Yogurt Bottle Production

A customer from Senegal required a customized lightweight glass bottle for yogurt, with a capacity of 143ml and an ambitious target weight of just 75g. This posed a significant challenge, as standard 143ml yogurt bottles typically weigh around 120g. Multiple glass manufacturers in China stated that such a low weight was unachievable on a standard production line, insisting that the weight must be increased.

However, upon discovering Newray’s advanced technology in lightweight bottle production, the customer turned to us for a solution. After reviewing the customer’s drawings, our designers acknowledged the difficulty but were determined to attempt a sample.

Engineering Innovation & Problem-Solving

To achieve the required weight while maintaining durability, Newray’s engineers, mold designers, and production team collaborated intensively. The mold factory engineers refined calculations multiple times, and the production department held special meetings to address the technical hurdles.

The initial sample, while successfully formed, presented challenges. Though the weight ranged between 75g and 77g, quality inspections revealed that certain bottle walls were too thin—measuring only 0.9mm to 1.5mm—raising concerns about breakage during transportation and use. Recognizing the need for structural optimization, our engineers refined the mold and conducted another trial production.

The second trial was a resounding success. The final bottle achieved the exact target weight of 75g while maintaining a wall thickness of 1.2mm to 1.8mm—ensuring durability without compromising on weight reduction.

Economic & Environmental Impact

This weight reduction had significant advantages. With an annual demand of 10 million bottles, Newray successfully reduced the weight by 37.5% from the conventional 120g to 75g, translating to over 25% cost savings for the customer. This competitive edge enabled the customer to dominate the local yogurt market while also contributing to sustainability by lowering carbon emissions.

Currently, the customer ships two full containers every two weeks, maintaining a strong business relationship with Newray. Encouraged by this success, the customer is now collaborating with us to develop two ultra-lightweight jam bottles, further pushing the boundaries of innovative glass packaging.
